What I have found that works for me when I get stuck, is go do things I'm either scared off, have been putting off, or completely outside my comfort zone. Brain researchers point out that when you do the same types of activities day in and day out, those neural pathways become "hardwired." ie habits. You literally stop thinking about them and go on automatic. Your idea about buying a laser cutter sounds great, but you also said it's within your skill-set. I'm NOT picking on you, but it sounds like you've already got some artistic talent so, while being fun (and potentially profitable) it may not stretch you.
Obviously I have no idea what your situation is...you may have people relying on you. You said travel wasn't an option.
You said you have some FU money but not RE. I might try and kill two birds with one stone (and one of the previous posters gave you the same idea)...maybe try a job completely and totally different from what you've done in the past. If you've been doing graphic design for a living....go try working as a lab assistant...or an electrician's helper...something so far out of your comfort zone the neurons in your brain actually squeak as they make new connections.
Make some cash, save your FU money and realize you may absolutely hate the new job...
In my earlier days...right out of college when I had not idea what I wanted to do...I went on an adventure streak. I hate heights so I went bungee jumping and skydiving. I rafted. I would intentionally try and get lost in a new city. Sounds silly, but it helped my figure things out.
I'm not suggesting you become a daredevil. But instead of thinking you're stuck, try reframing this as an opportunity to surprise the shit out of your loved ones and create some excellent stories to tell your friends.
Friend, "So Anna, what have you been doing since you're not working at SHITTYCOMPANY any more?"
Anna, "I've been.. (WRITING ARTICLES FOR OUTSIDE MAGAZINE...LEARNING TO DRAW BLOOD FROM BABOONS....BUILDING HOUSES FOR HABITAT FOR HUMANITY....HELPING XYZ CANDIDATE RUN FOR PRESIDENT)"
Friend, "Holy Shit!" (Eyes Bug Out!)
Really, this is not you being stuck, just getting ready to grow and expand into a new and different direction!
